ROTARY FAN.

Application filed December 6, 1913.

To all whom it may concern Be it known that I, VVAsABURow TAKE- SUYE, asubject of the Emperor of Japan, residing at Ogden, in the county ofl/Veber and State of Utah, have invented new and useful Improvements inRotary Fans, of which the following is a specification.

The invention has for one of its principal objects to enable theincorporation of a manually operated rotary fan in the handle of asunshade, whereby in sultry weather, not only may the handle bemanipulated to shield the user from the sun, but by a simple movement ofthe fingers which will not interfere with the grasp on the handle, arotary fan on the side of the handle may be used to produce a coolingbreeze.

A further important aim is to simplify the construction of the frame forthe mechanism and the method of mounting it whereby it is adaptedpeculiarly for the present use.

A further important object is to present such an arrangement of theparts that a symmetrical casing may inclose them in a form and sizewhich will be without objections as a part of an umbrella or the like.

. Additional objects and advantages will appear, some of which will beapparent from the following description and from the drawings, in which,

Figure 1 is a side view of a sunshade having a handle constructed inaccordance with my invention, Fig. 2 is a detail longitudinal sectionalview of the mechanism. Fig. 3 is a side view of the mechanism and frame,the casing in section, Fig. 4C is a cross section of the handle. Fig. 5is a detail of the handle showing the method of use. Fig. 6, is a detailof a modified hand rest,.showing a hand engaged therewith, Fig. 7, is adetail of the ferrule structure at the upper end of the frame, Fig. 8,is an outer end view thereof, Fig. 9, is a fragmentary view of a handleof modified construction.

There is illustrated a sunshade or umbrella 10, of any usualconstruction as re gards the canopy and supports, the handle 11 ofwhich, however is preferably attached to the stem by means of a screwthreaded shank 12. The handle may approximate the proportions of theusual umbrella or parasol handle, and comprises a symmetrical grip 13 inwhich there is secured the two sides of a frame 1& which comprises twopieces of thin strap metal suitably spaced Specification of LettersPatent.

and apertured for the mounting of a train of gears to be described indetail, the upper ends of the pieces being inset rounded and threadedfor engagement in the stem of the umbrella. A shaft 16 is mountedrevolubly closely adjacent the upper end of the frame 1 being carried insuitable apertures in the side pieces thereof, and a small gear 17 issecured thereon. The shaft has a squared end projecting through theframe, upon which the correspondingly apertured hub 18 of a smallscrew-blade fan may be pressed and frictionally held. A double gear 19is mounted revolubly below the shaft 16, the large member of which ismeshed with the gear 17, and the small member of which is in mesh with alarge gear 20 revoluble upon a shaft 21, which latter is also mountedrevolubly in the frame 14. Fixed upon this shaft and serving to checkthe gear 20 against sliding movement in that direction, there is aratchet wheel 22, engaged by a pawl 23 on the gear 20 the pawl beingpressed by a spring 24 for proper op eration. On the opposite side ofthe gear .20 a small gear 25 is fixed upon the shaft 21.

The small gears above mentioned may be of the usual clock type. The gear25 is engaged by a gear segment 26 mounted between the side pieces ofthe frame 1 1 closely adjacent the grip 13 against which it strikes atone limit of its movement. The segment is engaged by a spring 27 havinga helix engaged around the shaft 28 carrying the segment, one arm of thespring being seated on the frame 14. This spring tends to move thesegment to that limit of its movement where it is checked by the grip at13. In this position it will be seen that the segment projects beyondthe frame 1% on one side only.

The handle illustrated happens to be of the plain rectilinear typerectangular in cross section, and tapered from its outer end. The sidepieces of the frame 1e are mortised therein and secured by screws orotherwise, whereby the frame is held in proper form to support the geartrain and operating segment. The spring 27 tends to move the segment forrotation of the gear 20 in the direction in which the dog will ride theratchet, and for operating the segment for engagement of the dog andconsequent operation of the gear train, an arm 29 is extended from thesegment on the side opposite that which is projected from the frameunder action close parallelism with the grip 13 when pressed to theinner limit of its movement,

of the spring, this arm being suitably offset from the axis of thesegment so as to lie in narrow slot or'channel 29, to receive the narrowpart of the arm so that the broad part lies nearly or quite fiush withthe grip, an inconspicuous catch 30 being mounted on the grip by whichthe arm is secured at the inner limit of its movement, which catch maybe of any suitable kind; A hand rest 31 is ormed on ne s de of t gripadapted to rest on the hand close to the base of the fore-finger, asshown in Fig, ,5, the

pressure of the thumb being sufficient to retain the grip within thepalm, and all the ig may here y e s d or operating he ar 29.- I

The fan blades are curved so as to propel a current of air'away from thehandle when 'geaa ot t w dmanipulat n f the a 2 an it is found hat thmentum of the fan and gears is suflicient to cause their continuousmovement with a comparatively slow oscillation of the arm 29 producing astrong current of air. Use of the article has also demonstrated that itis no i fi lt er awk to P perly eupport a sunshade and at the same timemanipulate the operating arm 29. r he r t 31 may be emi te i esire a h ve epp rt y r p ng th g ip with some of the fingers while others areutilized to operate the arm 29 which need not be pressed entirelyagainst the grip for satisfactory operation ,of the fan. It will be alsofound practicable to provide a substitute for the rest 31 which will atthe same time be an embellishment, by providing a silk cord loop 32fixed on the outer end of the grip and of a length to allow insertion ofthe hand therethrough while the handle is grasped, an ornamental tasselbeing fixed at the outer part of the loop. A casing 33 somewhatpear-shaped and quite small, formed of any suitable material and fixedto the frame 14, completely incloses the mecha'- nism, and adds to theattractiveness of the handle. I i i The manner in which the side piecesof the frame are utilized to form a threaded shank for screwing into aparasol or umbrella Coplei of this patent may be pbtai ned for stem isparticularly eifective'and economical.

The sides arebent toward each other imme diately above the small gear 17and extend ed in parallel relation. These parallel parts are initiallymade slightly broader than the opening for which they are to be fitted.They may be bent into semicircular form, transversely, at their outerparts so that when put together they form a round shank and when this isthreaded it possesses ample streng h for thee te hme t e th hand T e atachm nt of th shank to the e eme a a ol n this-way would. he ufii ieh thold he f ame n t rm Withe it pe ial fe tenihg u as h t ie e emhedied ama screw r rivet. has been. ee he eeeer hese pa ts og t so that the hanle e m ch ni m may he eta hed from e her el a d used ar a ten el ne,when it ie 7. 1 3 fiie ent as a hair drier e fer et e Se Where treng daft i desi ed: ta a s f e ers may al o h n ed e ere eht'the I si of t eframe h m bein re s d in altheugh t ese are h b lie ed. eee et j Thereis illustrated in Fig.- 9 eh da eeon of e dev e-fie era-9m 9 ate hav nga e e k at ts ent r P ri, the creek eing sre ved e its inner side nd thee er 9-" Whieh i a a e h h re e n th ame ma ne e the l er ?.h e itsouter end disposed for oscillation the gro v The g eeve t p het. e t rnd ef h 3 are he e lf n of th v r ay he i Way. iab ty i h l er emh a din delicate fahr-ics in the garments ,of'the me t ther h 1h 'Phi user isobviated.
